PATENT OFFIcIt- ADDISON V. SANFORD, OF ELMIRA, NEW YORK.

ACETYLENE-G AS GENERATOR.

SPEGIFICATIONforming' part of Letters Patent No. 763,638, dated June 28, 1904.

i Application filed July 27, 1903. Serial No. 167,155. (No model.)

To a w/wm it-may concern:

Be it known that I, AD ISON V. SANFORD, a citizen of the United States, residing in the city of Elmira, in the county of Ohemung and State of New York, have invented certain new and useful Improvements in Acetylene-Gas Grenerators, of which the following is a specification.

This invention relates to acetylene-gas generators; and it has for its object to provide a generator of this class in which the production of gas of a plant maybe increased without the rebuilding of'the entire plant.

Another object is to improve the means for operating the 'carbid-holders.

Still another object is to provide antim proved means for delivering the gas from th generator to the gasometer.

- Other objects and advantages will appear in the following description and will be par ticularly pointed out in the appended claims. In the drawings, Figure 1 is a top plan View of the plant. Fig. 2 is a vertical section on the line 2 2, Fig. 1, in the direction of the arrows Fig. 3 is a perspective View of two of the generator-units. Fig. 4 is a vertical sectional view of one of the carbid-holders, and Fig. 5 is a detail perspective view of the means for dropping or feeding the carbid. Fig. 6is a detail view of the mechanism for operating the carbid-holders from the gasometer.

The machine employs a plurality of generator units, each consisting of a chamber 1, having bottom walls which decline from the sides to center and from the rear wall to the front wall, which is provided with an outletspout 2. Connected to the front wall of each chamber by a valved pipe 3 is a water-filling funnel 4. A plurality of carbid-holders are arranged in two parallel rows on the top of each generator unit and consist of circular vertical chambers 5, bolted to the top of the generating-chamber 1, closed at their tops by caps 6 and having flanges7 depending into the generating-chamber to the liquid-line.

Surmounting the generating-chamber 1 between the two parallel series of carbid-holders is a gas-chamber 8, into which extends one end of a pipe 9, which then passes downwardly through the liquid in the generatingchamber 1 and through the rear wall thereof to the gas-seal 10, into which it projects to beneath the liquid-line. Extending from the gas-seal above the liquid-line is a pipe 11, provided with avalve 12, which prevents back pressure. Each one of the valve-pipes 11 from each of the generator units connects with a sectional pipe 12*, (see Fig. 1,) which extends parallel with said units and into the ordinary condensing-chamber 13 beneath the gasometer 14, which may be of any approved construction. To obtain the same level .of water in the several. gas-seals that is in the condensing-chamber 13, a pipe 15 connects To operate the carbid-holderaan arm 16,

bifurcated at'its end 17, is secured to the gasometer-bell and has pivoted in itsbifurcation a dog 18, weighted at one end 19 anollimited in its movement by pins 19 19 This dog 18 is adapted for engagement with an endless belt 20, having lugs 20 upon each side thereof connected by bars 20 said belt passing over two pulleys 21 22, secured to a support 23, and one of said pulleys 21 being geared to a shaft 24, supported on one side of one of the generator units by means of gear-wheel 21 and pinion 24. The shaft 24 projects at its ends from the front and the back of the generatingchamber 1 and has mounted thereon gears 25 and 26, over which pass chains or cables 27 28, each carrying two equidistant projections 29, which on onebelt are arranged slightly in advance of those on the other. These chains or cables 27 28 also pass over gears 30 31 on a shaft 32, which is mounted on the end of the system of generator units opposite to that on which the shaft 24 is mounted.

In the bottom of the carbid-holders 5 are arranged hinged drop-valves 33, from each of which extend shafts 34, having arms 35 at an angle thereto, and pivoted to said arms 35 are trips 35", which when the drop-valves 33 are closed rest upon the tracks 30.

The operation of my invention is as follows: The carbid-holders and -the gasometer being filled, when the gasometer-bell lowers, owing to a consumption of some of the gas therein, I00

the weighted dog 18 contacts with the bars 2O on the endless belt 20 and said belt is moved. If only a small amount of gas is consumed, the belt moves only a slight distance; but'if a great amount of gas is consumed the bell, owing to its length and consequent duration of the contact with the Weighted dog, moves a greater distance. In moving, the belt being geared to the shaft 2& rotates said shaft, which moves the chains 27 28 and their projections 29, which owing to the projections on one belt being in advance of those on the other alternately engage on opposite sides of the generator units with the trips 35, supported upon said tracks 36, and move them rearwardly ofi? said tracks 36, whereby the valves 33 are permitted to drop, and thus feed charges to the generator-chambers 1. The gas generated upon the feeding of a charge of car bid passes through the gas-chamber 8, pipe 9, seal 10, valve-pipe 11, sectional pipe 12 to the condensing-chamber l3 and into the gasometer, the bell of which it raises, said bell carrying with it the weighted dog 18, which passes by the belt 20 Without operating the same.

It will be seen that generating units may be added to or taken from the system Without disassembling the whole plant. All that is necessary to be done is to lengthen or shorten the chains or cables 27 28 and add to or take another section from the pipe 12.

Having thus described my invention, what I claim is 1. In an acetylene-gas generator, a generator unit having two rows of carbid-holders, and means for alternately operating the carbid-holders in each row comprising two endless chains.

2. In an acetylene-gas generator, the combination of a plurality of rows of carbid-holders, and a plurality of endless chains provided with projections adapted to operate holders in different rows at each successive movement of all the chains.

3. In an acetylene-gas generator, the combination of a carbid-holder, a hinged dropvalve in said holder, a shaft extending from said valve, an arm at an angle to the shaft, a trip hinged to said arm, means supporting said trip, and means for moving said trip from its support to feed the carbid.

4:. In an acetylene-gas generator, the combination of a row of carbid-holders, hinged drop-valves in said holders, shafts extendingfrom said valves, arms extending from the shafts, trips hinged to said arms, atrack supporting said trips, and an endless chain provided with a projection movable on the track to remove the trips therefrom.

5. In an acetylene-gas generator, the combination of a plurality of rows of carbid-holdtending from said shafts, trips hinged to said arms, two tracks for supporting the trips,

and two endless chains provided with projections adapted to remove the trips from the tracks.

7. In an acetylene-gas generator, the com- I bination of a plurality of rows of carbid-holders, a plurality of endless chains for operating said carbid-holders, and shafts at the ends of the rows of carbid-holders for operating said chains together.

The foregoing specification signed this 21st day of July, 1903.
